Test Usage

PM-Scl antibodies are found in patients with homogenous overlap connective tissue disease characterized by Raynaud’s phenomenon, scleroderma, myositis, arthritis and pulmonary restriction. The presence of PM-Scl autoantibodies is a good prognostic sign unlike the poor prognosis seen with other myositis and systemic sclerosis-specific antibodies.
